The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.

Kogaja-jima volcano forms a small island located NW of Nakano-shima, Ryukyu Islands, Japan.
It contains andesitic lava domes and it is not known if the volcano is still to be considered active or not, i.e. if there have been eruptions in the past 10,000 years.
Its name Kogaja-jima means "Little Gaja Island", as it is ESE of the larger Gaja-jima stratovolcano. There is weak fumarolic activity in locations at the coastal cliffs.

Introduction to Plate Tectonics: The Earth's upper, rigid layer is broken into several plates which are in constant motion to one another. Most earthquakes and volcanoes occur as result of these plate boundaries.

Kelut volcano photos: A new lava dome grew inside the crater lake during the effusive eruption in late 2007, replacing most of the lake. Watch the birth of a new mountain!
